' SPECIFICATION.

I, WILLIAM BURTON, of the town of Lake, in the county of Newton andState of Indiana, have invented certain new and useful Improvements inGrading and DitchingIlows, of which the following is a full description,'reference being had to the accompanying drawing making a part of thisspeciication, in which- Figures l and 2 represent, in perspective, theditching-plow with clevis attachment; Fig. 3, section showingthe.adjustable and hinged connection of the mold-board; Fig. 4,crosssection, showing the front brace of the adjustable mold-board 5lFig. 5, section of rear end of the adjustable mold-board with harrowattachment; Figs. 6 and 7, details, showing the Inode of attaching anddetaching the land-side; Fig. 8, cross-section, showing the rear braceof the adjustable mold-boards; and Fig. 9, section of land-side withplatform attached.

The object of my invention is to construct a A v plow with an adjustableextension to the moldboard, so that it can be used for grading orditching without carrying belts or gearing of any kind; and its natureconsists in the application of two or more adjustable extensions to themold-board so that they can be adjusted toward or from the land-side,and with reference to the front or fixed mold-board 5 and also so thatthey will yield or move up and down to conform to the cutting of theplow; in the application of a platform to the land-side to enable theoperator to ride and keep the extended land-side down 5 in theapplication of v a harrow or iinisher to the rear end of the adjustablemold-board; and in an improvement in the clevis, so that the tipping ofthe plow sidewise will not affect the draft.

In the drawing, A represents the beam5 B, colter or small front plow 5C, plowshare; D, mold-board 5 E, curved brace 5 F, plow-handles 5 G,extended land-side; H, platform mounted thereon; I, front section of theadjustable mold-board; J, main section; L, additional section, to beused or not, as occasion requires; M, upper section or part ofmold-board J to give said mold-board a concave face; N, harrowonsmoother 5 O, frontface of the adjustable mold-board; P, land-sidebrace extending forward to the beam 5 Q, rear brace of mold-board5 Y R,detachable brace for supporting the additional section when used; a,brace for support- Specification forming part of Letters Patent No.123,613, dated Februaryd, 1872.

by means of which the brace Q f can be extended or contracted; z', hingeon land-side; j, hinge on land-side for brace It; k, joint in the facingof the land-side; l, joint in the body of the land-side; m, plate oversaid joint; a, bolts; o, land-side hinge for brace O 5 19, permanentbrace between the land-side and mold-board D5 q, hooks and eyes forconnecting additional mold-board L or harrowN with the mold-board J 5 r,key for locking the same; s, clevis 5 t a, links on clevis; o,swivel-coupling; w, brace-rod, connected with the beam for holding theouter end of the harrow N in position 5 x, holes at the inner end of thebracerod e, by means .of which the vertical position of the mold-board jis regulated. As I use from six to eight horses to operate this plow,all of its parts are necessarily made strong. The plow C D is madesomewhat larger than ordinary plows, and is strongly braced. The curvedbrace E, to which the beam is attached, passes from thefront of the plowaround to the back end of the beam, and from there I to the land-side,which gives a strong connection for the beam and a strong support forthe extended land-side. I also apply an additional brace, I), from thebeam to the land-side back of E, as shown in Fig. l. The rst section ofthe adjustable mold-board, as shown, is made short; but it may be madelonger, if desired, and, if made longer, an additional brace will beneeded. I prefer to make it short, as shown. It is connected with themold-board D by the single bolt b, supported at its inner end by thebrace a so as to give the adjustable mold-board an easy verticalmovement. It is adjustable up and down relative to the mold-board' D byholes, shown in dotted lines at Fig. 3. The mold-board J is attached toI by means of the hinge c d, shown also at Fig. 3, by means of whichsaid hinge the board J may be swung in or out by the adjustable braces OQ I usually give the board J a backing of wood so as not to make itheavy, and at the top I apA ply a separate sectionpn, or curve over thetop of the face-plate, as shown at Fig. 4, to prevent the dirt fromfalling over When the moldboard is in an elevated. position. y Thebraces O Q are made adjustable by means of clasps and pinsas shown. Thebrace Q is provided with an upper arm, e, and a series of holes, w, bymeans of which the position of the board J is regulated so as to insureits proper operation when theplowis Worked on the surface or down in adeep ditch. Wlien an unusual Width of ditching or grading is required Iattach an additional mold-board, L, to J by means of the hooks and eyesg and key r, which is supported from the land-side by the brace R, whichsaid brace is notidjustable in length, but may be made so, if desired.When grading for hedge, roads, &c., or finished Work is required, inplace of L, I attach the harrow or smoother N, and support it from thebeam by the bracerod i0. Its position, as shown at Fig. 5, is at ornearly at right angles With the board J, and its lower edge is inclinedbackward so as to neatly finish the Work. It will not be necessary toattach this smoother, except at the last round ofthe plow. The platformH is attached near the rear end of the land-side; and it not onlysupports the operator, but is very important in holding` the land-sidedown so as to afford a proper support for the braces Q or R, and insurethe proper carrying out of the dirt bythe mold-boards. rlhe part s oftheclevis iS attached to the beam in the usual manner, and' is providedwith the usual means for regulating the line of draft. The coupling o isatta ched to this by a bolt, and its front end made to swivel With thelink t. The links t u are connected together by a bolt, -shown at Fig.2, so as to make them flexible. By this const-ruc-V tion ofthe clevisand its connections with the double tree or draft-bar the draft is notaffected by any rocking movement of the plow. The

`braces 0, Q, and R are connected with the land-side and mold-boards byhinged connection-s o, i, j, and g, as shown, so that the Verticalmovements of the mold-boards shall not aect the land-side.

By making and attaching the share C in the usual Way it can be changedor sharpened at pleasure; and by making the Vextended landside in two ormore sections it is easily repaired When broken, as it can be takenapart at the joints Z and k.

What I claim as new, and desire to secure by Letters Patent, is

1.An adjustable mold-board composed of three or more sections,substantially as and for the purposes specified,

2. The combination of the extended landside with the adjustablemold-board, made in two or more sections, and the braces O, Q, and e foradjusting the Vertical and lateral pitch of the mold-board,substantially as specified.

3. The combination ofthe mold-board I with the fixed mold-board D, whenconnected by a single pivot or pin, b, so that the rear moldboard mayfollow the inequalities of the ground Without disturbing the plow G D,substantially as described.

4; The barrow or nishing section Nin combination with the adjustableboard J, substantially as and for the purposes specilied.
